For US buyers, I would recommend the TCL P605/7:
https://www.rtings.com/tv/reviews/tcl/p-series-2017-p607After extensive research, this is probably the best 4K HDR television you can buy for the money. After this model, all prices pretty much go above $1,000 and the money is NOT worth it. I just got mine so I'll post back in a couple weeks with how it's actually working for me. I'll say for now that out of the box it looks superb.
Edit: To answer the poster above me, input lag is basically non existent on this model. It boasts one of the lowest (if not the lowest) in its price range.
